Abstract
Systems and methods are provided to quantify the geometric change of a projectile during ballistic flight using a camera/tracker video system. Image processing tools are used to segment the shape of the projectile in each frame of a launch video, which allows the length to be calculated with sub-pixel accuracy. Subsequent automated analysis uses a baseline length history of a constant length projectile to correct for variations in measured length due to system layout and camera location.
